Help to make calculaions

I developed an app to manage the stock of one product. Now I need that app to have the capacity to manage more than two identical products, but I would like to do all this on the same app.

When the product enters in stock, the price and the quantity in kg is inserted, however I have some variable parameters for each one of these products:

- If the product is too green it's discounted a percentage from the price
- If the product is too ripe it's discounted a value per kg
- If the product is delivered within a certain date the price is one, if it is delivered after that date it is cheaper (the price 1 and 2 are always the same )
- The product can have a bonus on the total of the document if the quality is good (the bónus is ever the same value). And it can have more than one bonus.
- In some cases the discount will be done over a calculation previously done based on one of the previous conditions (e.g. after the discount for being too green)

All products have different conditions.

I have thought about using a formula scheme but I got a little bit lost. I would appreciate any idea to help.

There is no smart method.
All you can do is to record the conditions for each product, then - product by product - walk through the calculations you partially have described, and you will end up with the final price for each product.

I agree there really is no "smart" method.

You need to think through which is the first one to test.

Does one of the criteria take precedence?

Are the discounts cumulative?

Some criteria are exclusive eg too green or too ripe.  Maybe could test them together if the discounts are the same or test 1 but only test the other if the first test fails.

THe best method would be to layout all the tests on paper then see which can be combined.

Are the conditions different for different products or just the values of the tests?
